understanding solar panels
Solar panels aredevices which can be useful for producing electricity from sun light. Solar panels are comprised of many individual photo voltaic cells organized in series. Each cell has the capacity to produce handful of voltage as a reaction to the incident sun rays over its surface.

What areand how do they work?
Solar panels are simply a collection of 60 or more solar cells. Panels can use different cell types and cell arrangements: Pro-tip: There are some benefits to using half-cut or shingled panels over conventional ones if you have shade that creeps up on thes through the day.
Why do solar panels have to be connected in series?
The cables must be chosen such that resistive power losses are minimal. The power dissipated across a cable is proportional to the square of the current flowing through the cable. Hence, as the current doubles, four times as much heat will be dissipated at the cables. Therefore, modern solar panels have connected all cells in series.
What is the difference between different types of solar panels?
鈥?The Solar Cells are connected in series via Busbars and Cross-Connectors. The primary difference across solar panels is the types of solar cells they utilize. A solar panel is broken into two cell types: monocrystalline and polycrystalline. Monocrystalline solar panels 鈥?Are made with silicon wafers cut from a single crystal.
What is the power output of a solar panel?
Solar panels are classified according to their rated power output in Watts. This rating is the amount of power the solar panel would be expected to produce in 1 peak sun hour. Different geographical locations receive different quantities of average peak sun hours per day.
